I like someone at work who's 2 years younger than me.
We're in different departments, and I usually see him once or twice a week. We have so much in common, he's one of the few people I feel like I could just talk to non stop.
We talk when we see each other in the office and occasionally on work chat, the chat is jokey and very mild teasing.
It's my birthday coming up so I mentioned I'd be going out with a few people if he wanted to come. He said it sounded really fun, and he'd be up for it.
Then the next time I saw him he asked when my birthday was.
He said to a mutual colleague I'm really nice and 'sweet' and we talk a lot.
He told me he likes talking to me.
It's hard to say, it could just be entirely friendly on his part. I felt him looking at me a certain way, but that could be all in my head or just meaningless.
